Are you searching for a reliable 12L scuba cylinder supplier that meets USA safety standards and your B2B budget? A 12L scuba cylinder is the industry-standard size for recreational and professional diving, offering a balanced air capacity (approx. 200 bar fill) without excessive weight. For import managers and wholesalers, the key questions are always: Is it DOT/ISO certified? What is the MOQ? Can I get OEM branding? How fast can you ship? This guide delivers data-backed answers, factory specifications, and compliance details for the 12L scuba cylinder market in 2026 — helping you make an informed sourcing decision.
Why Many Importers Struggle with Scuba Cylinder Sourcing — and How to Fix It
The global diving equipment supply chain faces three persistent pain points in 2026:
- 1. Certification confusion: Non-compliant cylinders are rejected at US ports. Buyers lose time and money.
- 2. Inconsistent quality from unknown factories: Wall thickness, valve threads, and hydrostatic test results vary wildly.
- 3. Long lead times & hidden logistics costs: Many suppliers quote FOB but fail to include container loading or hazmat fees.
Our approach: As a fully integrated factory in Zhuzhou, Hunan, Zhuzhou XingYe Chemical controls every step — from steel sourcing to final hydro test. We provide 12L scuba cylinders with full traceability, DOT/ISO/CE certifications, and transparent FOB/CIF terms. No middlemen, no surprises.
12L Scuba Cylinder — Technical Specifications & Compliance
Below are the standard parameters for our 12L scuba cylinder. (All data is typical and may vary slightly per batch. Please refer to actual order confirmation.)
| Parameter | Specification |
|---|---|
| Water Capacity | 12 Liters (approx. 0.42 cu ft) |
| Working Pressure | 200 bar / 3000 psi |
| Test Pressure | 300 bar / 4350 psi |
| Cylinder Material | High-tensile steel 34CrMo4 / 30CrMo |
| Valve Connection | 5/8" UNF (CGA 347 / DIN 477 compatible) |
| Weight (empty) | Approx. 12.5 kg (27.5 lbs) |
| Weight (full) | Approx. 14.9 kg (32.8 lbs) |
| Certifications | DOT-SP 10915 / ISO 9809-1 / CE 0102 / TPED |
| Hydrostatic Test Interval | 5 years (USA standard) |
| Finish | Epoxy powder coating (black, white, or custom RAL) |
Why this matters for B2B buyers: All our 12L cylinders are individually hydrostatically tested, serial-numbered, and come with a full COA (Certificate of Analysis) and mill test report. We maintain a zero-rejection rate for DOT compliance audits in 2025-2026.
12L vs. Other Common Cylinder Sizes — Which Fits Your Market?
| Cylinder Size | Air Volume (at 200 bar) | Typical Use Case | Best for Wholesale? |
|---|---|---|---|
| 7L | ~1,400 liters | Travel, side-mount, pony bottle | Niche |
| 10L | ~2,000 liters | Single-tank recreational diving | Moderate |
| 12L (our focus) | ~2,400 liters | Standard single-tank, advanced recreational, light technical | High demand |
| 15L | ~3,000 liters | Technical, twin-set, commercial | Moderate |
The 12L scuba cylinder hits the sweet spot for USA divers: enough air for a standard 45-60 minute dive, yet light enough for single-tank boat dives. For wholesalers, it represents the highest inventory turnover in the recreational segment.

Mike H. — Dive Shop Owner, Florida
📅 Order: 200 pcs 12L cylinders, June 2025
"We switched to XingYe after our previous supplier kept missing delivery dates. The 12L cylinders arrived in perfect condition, all with valid DOT stamps. The hydro test reports were included with every batch — saved us hours of paperwork. Our rental fleet has been running these for 8 months with zero valve issues."
Sarah L. — Procurement Manager, Caribbean Resort Chain
📅 Recurring orders, 2024-2026
"We manage 4 dive resorts and needed a consistent supply of cylinders that could handle tropical humidity and saltwater. XingYe's 12L cylinders have a thicker powder coating than what we previously used — they look new after 18 months. Their team also helped us with custom color coding for each resort. Reliable partner."
David P. — Sourcing Agent, Dive Equipment Wholesaler, California
📅 Order: 1,000 pcs mixed sizes, Q4 2025
"Price was competitive but the real win was the OEM service. They laser-engraved our brand, created custom packaging, and handled the DOT certification paperwork. Our retail clients love the quality. Lead times were exactly as quoted — 28 days from deposit to FOB. Will order again."
Tom R. — Technical Diving Instructor, Texas
📅 Personal purchase: 5 pcs 12L cylinders
"I use these for my advanced nitrox classes. The 12L size is perfect for teaching gas planning. Cylinders arrived with clean internal finish, no debris. Threads are smooth, valves seat properly. Comparable to major US brands at a much better price point for bulk training sets."
